It could be useful in a routing table:
Destination Gateway Genmask Flags Metric Ref Use Iface
188.8.131.52 0.0.0.0 255.255.255.255 U 0 0 0 eth1
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
The destination could do the same in reverse, so the conversation would
only be between those two systems.
